Abstract

In this stirrer, the stirrer arms (3, 3a) are arranged radially on the drive shaft (2) and are provided with plates (4, 4a). On these plates, stirring elements (5, 6) are arranged at a distance and inclined relative to one another, in such a way that their shadow areas overlap in the direction of revolution or at least are almost contiguous.
